Makeshift Weapon
I think Jackie handled himself very well in a similar situation in "Rumble In The Bronx".
Using a car antaena as a weapon might not be a bad strategy if there is enough time to secure it before they swarm on you. You might be able to back them up enough to clear a path for you to run to safety.
Even better if you have time to get in your car and drive straight at them.
I don't think Wing Chun is so limited that I can't do it when I wrestle, box, kickbox, or fight by MMA rules, nor am I so limited a student that I can't improve by training in each of those forums. -Andrew S
A good instructor encourages his students to question things, think for themselves and determine their own solutions to problems. They give advice, rather than acting as a vehicle for the transmission of dogma.
